Robert Wallace, the former director of the CIA's Office of Technical Service, discusses his new book Spycraft: The Secret History of the CIA's Spytechs from Communism to Al-Qaeda. Spycraft tells the story of how technology that would not appear in the public marketplace until decades later was often used to further the American intelligence-gathering cause. This event took place on October 8, 2009, at the Central Library, 14 W. 10th Street, Kansas City, MO.
